I had almost no side effects on Tamoxifen but have not been so lucky with Femara. At first I had a lot of joint pain but through trial and error (and maybe the passing of time so my body has adjusted) have got on top of that. I take Curcumin (from Turmeric) as a supplement and it has made a big difference to the joint pain.
The most worrying side effect for me has been the effect on my bone density. Again though, I have found a solution (I hope) that works for me. I now do weightlifting two times a week and this is helping to improve my bone density. It might be worth having your bone density tested before deciding on your path. Having your ovaries removed (as I found out) is not good for your bone health! You might be fine though but worth checking with your doctors.
The other issue is a sensitive one, but vaginal atrophy is also a side effect of this treatment. But again there are ways to help this too.
We are all different and some people have no side effects at all on these drugs. The best thing is finding info from the people on this network who are living through these treatments. That is how I have found the help I have needed to live well with minimum effects from my hormones or lack there of!
